With Texas Instruments SimpleLink Wi-Fi CC3000 and Qualcomm Atheros AR4100P embedded Wi-Fi processors that fully handle Wi-Fi internally, and transfer data to an MCU with an SPI interface, and solutions such as Electric Imp, there are already ways to add Wi-Fi at relatively low cost to appliances. There’s now another solution available on the market with Lantronix xPico Wi-Fi Module.

- Relative Humidity: 0% to 90% non-condensing
- Certifications – FCC Class B, UL and EN EMC, Japan
- Dimensions – 24mm (L) x 16.5mm (W) x 5.64mm (H)
- Weight – 2.5g
The module also comes with a 5-Year limited warranty.
The company also provides xPico Wi-Fi development kit ($136.10 – Ref: XPW100100K-01) for evaluation or development comprised of the following items:
- xPico Evaluation Board with xPico Wi-Fi module and mounting clip
- 2dBi, Whip Antenna with RP SMA connector (930-033-R)
- 1.5 to 2.5dBi, PCB Strip Antenna with 50mm U.FL cable (930-099-R)
- 5Vdc Wall-mount power supply AC/DC, 1A with mini-USB connector
The board itself features the xPico Wi-Fi module, and Ethernet port, a serial connector (DB9), u.FL and SMA antenna sockets, a USB device socket, and for power: a micro USB port, a battery port, and an On/Off switch.
Embedded Star reports the module is available now, and pricing starts at $27.80 for 5,000 unit quantities. You can find more documentation about xPico Wi-Fi module, and development board on Lantronix xPico Wi-Fi documentation page.

I don’t see this making any impact in the consumer/hobby market at this price and with no SDK.
A company called acal BFi will host a webninar about xPico Wifi on March 18:
They also offer free kits to people with projects they like, and there’s also 20% discount on the devkit for a limited period of time:
